As more and more small businesses are discovering the benefits of high-speed connections to the Internet, they are also looking for ways to use the Internet as a way to communicate within their company. Instead of using leased-lines to connect remotely, the Internet is seen as the new medium to cost-effectively transmit company data. Using a public domain to send private data has severe security concerns and can create liabilities, especially when unethical persons use methods to read or sniff the valuable data being transmitted. An effective way to prevent private data from being read is to scramble or encrypt the data prior to being sent, and then unscrambling or decrypting the data at the intended destination. Establishing this encrypting and decrypting methodology over the public Internet is known as setting up a Virtual Private Network, or VPN. The Firewall offers the ability to establish these VPN tunnels, allowing for a company to provide secure access to intranet data over the internet, Further more the data in the VPN tunnel is compressed and thus maximizing the transfer speed. VPN Technologies offer cost-effective, scalable and secure networking solutions to meet your specific business needs. VPN Solutions offer clear benefits, including operational flexibility, easy customer access and therefore, improved service and streamlined sharing of information and business applications Hardware Requirements: Processor Pentium II 300 MHZ Memory - 256Mb 10 GB HDD WAN port - x10/100baset LAN port - 1x10/100BaseT DMZ port 1 x 10/100baseT Linux NMS Johannesburg Firewall VPN server WS Netware Marconi ADSL Router Wynberg Durban Firewall VPN server W2K server IIS Webserver MS SQL Marconi ADSL Router Netware 512/256 ADSL 512/256 ADSL Mauritius User conenct via VPN ISP Mailserver Webservers ISP Network Remote User conenct via VPN 512/256 ADSL WS Cape Town Firewall VPN server Marconi ADSL Router Contact: Jaco Lange PE Netware

6 Attachment (2) MailScanner Spam (unsolicited commercial ) accounts for 35% of all messages and is rapidly increasing. 1 in 150 messages contains a virus, costing many billions of dollars around the world every year. There are currently something in the order of 15,000-20,000 sites using MailScanner. The entire log can be viewed on a webpage MailScanner is already a highly-respected open source e- mail security system, with more users than AOL and Hotmail combined, and this new release increases its stability and performance. It processes 500 million messages every day, removing 2 million viruses and identifying 75 million spam messages. MailScanner is used at 20,000 sites around the world protecting top government departments, commercial corporations and educational institutions. MailScanner scans all for viruses, spam and attacks against security vulnerabilities. It is not tied to any particular virus scanner, but can be used with any combination of 14 different virus scanners, allowing sites to choose the "best of breed" virus scanner. Being open source, site administrators can audit and verify the integrity of the system. Its role is a major part in the security of a network, and so it must act as a trusted service. The only way to achieve the required level of trust is to be open source, an approach the commercial suppliers are not willing to take. MailScanner has been developed in a world-leading Electronics and Computer Science Department at the University of Southampton. MailScanner users SpamAssassin to identify SPAM, the spam-identification tactics used include: header analysis: spammers use a number of tricks to mask their identities, fool you into thinking they've sent a valid mail, or fool you into thinking you must have subscribed at some stage. SpamAssassin tries to spot these. text analysis: again, spam mails often have a characteristic style (to put it politely), and some characteristic disclaimers and CYA text. SpamAssassin can spot these, too. blacklists: SpamAssassin supports many useful existing blacklists, such as mail-abuse.org, ordb.org or others. Mail Relayed Daily Graph Hardware Requirements: Pentium 4 2 GHZ 512Mb RAM 40 GB Hard disk 1 X Network card Spam Identified Daily Graph Razor: Vipul's Razor is a collaborative spamtracking database, which works by taking a signature of spam messages.

7 Attachment (3) BackupPC is a high-performance, enterprise-grade system for backing up Linux andwinxx PCs and laptops to a server's disk. BackupPC is highly configurable A clever pooling scheme minimizes disk storage and disk I/O. Identical files across multiple backups of the same or different PCs are stored only once resulting in substantial savings in disk storage and disk I/O. One example of disk use: 95 latops with each full backup averaging 3.6GB each, and each incremental averaging about 0.3GB. Storing three weekly full backups and six incremental backups per laptop is around 1200GB of raw data, but because of pooling and compression only 150GB is needed. Optional compression support further reducing disk storage. Since only new files (not already pooled) need to be compressed, there is only a modest impact on CPU time. No client-side software is needed. The standard smb protocol is used to extract backup data on WinXX clients. On linux clients, tar over ssh/rsh/nfs is used to backup the data. With version 2.0.0, rsync is also supported on any client that has rsync or rysncd. A powerful web (http/cgi) user interface allows administrators to view log files, configuration, current status and allows users to initiate and cancel backups and browse and restore files from backups. A full set of restore options is supported, including direct restore (via smbclient, tar, or rsync/rsyncd) or downloading a zip or tar file. Supports mobile environments where laptops are only intermittently connected to the network and have dynamic IP addresses (DHCP). Flexible configuration parameters allow multiple backups to be performed in parallel, specification of which shares to backup, which directories to backup or not backup, various schedules for full and incremental backups, schedules for reminders to users and so on. Configuration parameters can be set system-wide or also on a per-pc basis. Users are sent periodic reminders if their PC has not recently been backed up. content, timing and policies are configurable. Tested on Linux, Freenix and Solaris hosts, and Linux, Win95, Win98, Win2000 and WinXP clients.
